1 / 16 page  AP7173 1.5A LOW DROPOUT LINEAR REGULATOR WITH PROGRAMMABLE SOFT-START AP7173 Rev. 7 1 of 16 OCTOBER 2009 DS31369 www.diodes.com © Diodes Incorporated • Low VIN and wide VIN range: 1.0V to 5.5V • Bias voltage (VVCC) range: 2.7V to 5.5V • Low VOUT range: 0.8V to 3.3V • Low dropout: 165mV typical at 1.5A, VVCC = 5V • 2% accuracy over line, load and temperature range • Power-Good (PG) output for supply monitoring and for sequencing of other supplies • Programmable soft-start provides linear voltage startup • Bias supply permits low VIN operation with good transient response • Stable with any output capacitor ≥ 2.2µF • DFN3030-10 and SOP-8L-EP: available in “Green” molding compound (No Br, Sb) • Lead-free finish/ RoHS Compliant (Note 1) The AP7173 is a 1.5A low-dropout (LDO) linear regulator that features a user-programmable soft-start, an enable input and a power-good output. The soft-start reduces inrush current of the load capacitors and minimizes stress on the input power source during start-up. The enable input and power-good output allow users to configure power management solutions that can meet the sequencing requirements of FPGAs, DSPs, and other applications with different start-up and power-down requirements. The AP7173 is stable with any type of output capacitor of 2.2µF or more. A precision reference and feedback control deliver 2% accuracy over load, line, and operating temperature ranges. The AP7173 is available in both DFN3030-10 and SOP-8L-EP packages. • PCs, Servers, Modems, and Set-Top-Boxes • FPGA Applications • DSP Core and I/O Voltages • Post-Regulation Applications • Applications With Sequencing Requirements Typical Application Circuit EN PG VCC IN OUT FB SS GND AP7173 R1 R2 R3 C1 C2 C3 VOUT VIN VVCC CSS Figure 1.
